Faulted basin is a kind of typical tectonic active basin, in which there are various kinds of tectonic slope-breaks controlled by different tectonic backgrounds and mechanisms. Based on the researches on Mesozoic and Cenozoic faulted basins in eastern China, classification system on structural slope-break of faulted basin is put forward, basic characteristics and forming mechanism of various kinds of structural slope-break have been described in detail and synthetic models of sequence stratigraphic development in continental faulted basin are set up in this paper. Structural slope-break in faulted basin can be divided into fault slope-break, bend slope-break, flexure slope-break and pivotal slope-break. The fault slope-break is controlled by syndepositional faulting within the basin, the formation of the bend slope-break is related to listric geometry of major boundary fault in faulted basin, while the flexure slope-break often results from activity of blind normal fault in the basin basement. Different from above three slope-breaks, the formation of the pivotal slope-break is a result of rotational tilting of hanging wall of normal fault, the development is mainly controlled by main boundary normal fault with steep dip and plane geometry. Development, distribution in space, evolution process and assemblage pattern of structural slope-break determind accommodation and sediment influx system in faulted basin, further it restricts sediment disperse process and distributional pattern of sand bodies in faulted basin. The researches on relationship between structural slope-break and depositional facies will be a great help to illustrate distribution of depositional systems and promote prediction availability of sand bodies in sedimentary basin.

断陷盆地是典型的构造活动型盆地 ,盆地中各种类型的坡折带均有其发育的构造背景和控制机制 .以中国东部中新生代断陷盆地的研究为基础 ,提出了断陷盆地构造坡折带的分类方案 ,描述了各类构造坡折带的基本特征和形成的构造机制 ,建立了陆相断陷盆地层序发育的综合模式 .断陷盆地中的构造坡折带可分为断坡带、弯折带、挠曲带和枢纽带 4种类型 .断坡带受控于断陷盆地内各种类型的同生断裂作用 ,弯折带则与主控边界断层的几何学形态密切相关 ,形成于铲式正断层控制的断层上盘内 ,而挠曲带与基底正断层的隐伏式活动有密切的关系 .上述 3种类型的构造坡折带都是由盆地上盘的变形作用所产生的 ,而枢纽带的发育则是盆地上盘的旋转掀斜作用引起的变位所致 ,同时这类坡折带发育于主边界断层为陡倾平面状正断层控制的断陷盆地内 .构造坡折带的发育特征、空间分布、演化过程和组合样式决定了盆地的可容空间和物源系统 ,因而制约了沉积物的分散过程和砂体的分布样式 .揭示构造坡折带与沉积相的展布关系 ,将有助于阐明盆地内部沉积体系分布规律 ,有效地进行砂体预测

The Bohai Sea area is one of the main hydrocarbon enrichment areas in Bohai Bay Basin. The exploration in Eeogene is greatly successful in recent years, but the exploration in Paleogene has not achieved a great breakthrough yet. For the Paleogene, the palaeo-geomorphology as a background of the sequence development controls both the sequence development and the genesis and distribution of the depositional system, for which the palaeo-geomorphology analysis could be a key and base for the middle-deep reservoir...

The Bohai Sea area is one of the main hydrocarbon enrichment areas in Bohai Bay Basin. The exploration in Eeogene is greatly successful in recent years, but the exploration in Paleogene has not achieved a great breakthrough yet. For the Paleogene, the palaeo-geomorphology as a background of the sequence development controls both the sequence development and the genesis and distribution of the depositional system, for which the palaeo-geomorphology analysis could be a key and base for the middle-deep reservoir prediction. The basic characteristics of palaeo-channel and palaeo-tectonic slope break and its control on depositional system in Bohai Sea Area are studied and the reservoir prediction of two blocks in the area is taken an example to delineate the application of the palaeo-channel and palaeo-tectonic slope break principle for reservoir prediction of Paleogene in detail.

近几年来,渤海海域新近系勘探获得了突破性进展,但古近系中深层勘探没有获得大的突破,关键原因之一在于中深层储集层预测困难。古近纪的古地貌作为层序发育的背景,不仅对层序的发育起着重要的控制作用,对沉积体系成因及其展布同样也有重要的控制作用,因此,古地貌分析是准确预测中深部储集层的关键和基础。阐述渤海海域古沟谷和古构造坡折的基本特征及其对沉积体系的控制作用,并以渤海海域两个区块为例,分别阐述了古沟谷即残留可容纳空间和古坡折理论在渤海古近系储集层预测中的作用。图9参8

Based on the studies of the Songliao Basin characterized by Cretaceous down-warping, of the Jurassic compressional flexural Junggar basin and of the Bohai Bay Basin characterized by Paleogene rifting, the multiple-grades slope break has developed in lacustrine basins of different origins. Their genetic types can be divided into tectonic slope break, depositional slope break and erodent slope break. The dominant agent of the slope break is tectogenesis, and the scale of slope breaks relates with the size of tectogenesis. The results of the study show that control of mutual grades slope breaks on atectonic traps mainly represent: 1) Atectonic traps develop close to mutual grades slope breaks, with beads-shaped distribution along the slope breaks. 2) In the longitudinal direction, the development of atectonic traps is characterized by the inheritance. 3) Different slope breaks and their different geographical positions can lead to different development types of atectonic traps. 4) A slope break can form different kinds of atectonic traps because of its great lateral variation. 5) The existence of mutual-grade slope breaks leads to different responses of erosion and deposition at different geographical positions in the basin. The oil source bed, reservoir and cap rock combination of atectonic traps is fine. 6) The oil-bearing condition of atectonic traps controlled by slope breaks is very favorable.

对准噶尔盆地西北缘地区侏罗系、东营凹陷下第三系、松辽盆地南部西斜坡等目的层系层序地层学的研究,认为断陷及坳陷盆地发育多级坡折带,按成因机制可分为构造坡折带、沉积坡折带和侵蚀坡折带。构造运动是坡折带发育的主控因素,而且其规模与构造运动大小息息相关。研究结果认为多级坡折带对非构造圈闭的控制主要表现为:1)非构造圈闭紧邻多级坡折带发育,沿着坡折带呈串珠状展布;2)非构造圈闭在纵向上发具有继承性的特点;3)非构造圈闭发育的类型随着坡折带和坡折带所处的地理位置的不同而不同;4)同一个坡折带在横向上存在较大的变化,可形成不同类型的非构造圈闭;5)多级坡折带的存在导致了在盆地的不同地理位置发生不同的沉积剥蚀响应,非构造圈闭的生、储、盖组合较好;6)坡折带控制下的非构造圈闭的含油性条件十分有利。
